I am getting ready to install my new aircompressr. I need to run a line from the garage to the basement. There is now way to keep the line within the confines of the house walls, I have to run it outside. What type of piping should I use. I want to run it under ground to protect it a little from the outside elements.

I also need to run the wiring along with the piping outside. Is there something special I need to do tothe wire, or is there an outside wire that I would need?
